BUILDING-BLOCK.

. Specification of Letters Patent.

Patented June 1'7, 1919.

Application filed October 24, 1918. Serial No. 259,474.

To all whom it may concern:

Be it known that I, ALBERT A. SMILEY, a citizen of the United States, residing at Albia, in the county of Monroe and State of Iowa, have invented certain new and useful Improvements in BuildingBlocks, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain improvements in concrete building blocks, and it is an object of the invention to provide a device of this general character with a metallic reinforcement embodying novel and improved means whereby an effective tying or bonding engagement may be had between each block of a course of blocks and also between each successive course of blocks thereby to produce a firm and durable structure.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved building blocks, whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwlse more convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, in which:

Figure 1 is a view partly in elevation and partly in section illustrating a plurality of blocks constructed in accordance with an embodiment o-fmy invention, and in assembled relation;

Fig. 2 is a view in perspective of a block constructed in accordance with an embodiment of my invention.

Fig. 3 'is a view in perspective of a block constructed in accordance with an embodiment of my invention of a type particularly adapted for use in the building of a silo or the like: and

Fig. 4 is aview in perspective of a block constructed in accordance with a further design.

As disclosed in the accompanying drawings, B denotes a block formed of concrete or other plastic material and which has embedded therein at substantially its center and extending longitudinally thereof the reinforcement R.

The reinforcement R is formed of a single length of material, preferably wire of requi forcement R and is bent to afford a loop 2.

The opposite end portion of the strand is disposed through said loo and extends across the reinforcement at substantially right angles to the longitudinal axis of the block and terminates exteriorly of the block B through a side face thereof. The extended portion 3 of the strand is of a length to be received between the opposite end portions of a pair of adjacent blocks B and is provided with a hook member 4 at its extremi-ty which extends through the loops 1 of said adjacent blocks. As is particularly illustrated in the accompanying drawings, it is to be noted that the loops 2 of the adjacent blocks are in overlying relation when the blocks are arranged in proper course.

The end faces of each of the block B is provided with a groove 4 in which the loop 1 is arranged, and in practice it is preferred that said grooves 4 be vertically disposed. The upper face of each of the blocks B is provided with a longitudinally disposed groove 5 in which seats a tongue or rib 6 disposed longitudinally along the lower face of an imposed block.

In Fig. 3 I disclose a block constructed in accordance with my invention, and wherein the same features are embodied as disclosed in Figs. 1 and 2 except that the block B is disposed longitudinally on the predetermined curvature so that the same may be particularly employed in the building of silos or similar structures.

In Fig. 4 I disclose a block also constructed substantially the same as hereinbefore set forth except that the block B" has its various faces square or the block B" is of a cube formation. I am disclosing this form, as it has been found in practice that a block of this design is often required in practice,

From the foregoing description, it is thought to be obvious that a building block constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility With which it may be assembled and operated, and

it will also be obvious that my inventionis susceptible of some change and modification Without departing fromthe prlnciples and spirit thereof, and for this reason I do not Wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed. v I claim :7 p 1. In combination with a building block,

a reinforcement embedded therein and formed of a sin 'le len th of material said reinforcement being substantially diamond shape With its end portions extending beyond the end faces of the block, said extended portions being formed into loops, an

end portion of the strand from Whichvthe reinforcement is produced extei'id ng transversely across the diamond shape and terminating exteriorly of the block.

2. In combination with a'building block, areinforcement embedded therein and formed of asingle length of material, said reinforcement being substantially diamond shape with its endportions extending beyond the end faces of the block, said extendedportions being formed into loops an end portion of the strand from which the reinforcement is produced extending transversely across the diamond shape and terminating exteriorly of the block, the opposite end portion of said strand being provided with a loop through Which said extended portion is disposed.

In testimony whereof I hereunto aflix my signature in the presence of two Witnesses. ALBERT A. SMILEY.
